JEE Main Chemistry question

Statement 1: One molar aqueous solution has always a higher concentration than one molal. Statement 2: The molality of a solution depends upon the density of the solution whereas molarity does not.

(A)Assertion is True, Reason is True; Reason is correct explanation for Assertion
(B)Assertion is True, Reason is True; Reason is not correct explanation for Assertion
(C)Assertion is True, Reason is FalseCorrect
(D)Assertion is False, Reason is True

Answer: (C)

Solution

For most common aqueous solutions (density at or above 1 g/mL), a 1 molar solution is numerically more concentrated than a 1 molal solution of the same solute, so Statement 1 is true (taken in this usual sense). However, Statement 2 has the dependence exactly
